MYSQL and PHP where any related row contains string - php

Question

I am having a small issue with MYSQL relations.
There is for every 1 value in table 1, there can be a multitude of values (0+) in table 2.
I am able to get all the data correctly, however, the issue comes when some values in table 2 differ, specifically the "taken up" field.
$sql = "
SELECT
accounts.name AS business,
accounts.industry AS style,
accounts_cstm.renewaldate_c AS ren_date,
accounts_cstm.nolongercontact_c AS NLC,
accounts_cstm.contactname_c AS person,
campaigns.name AS campaign,
users.first_name AS exec_fn,
users.last_name AS exec_sn,
email_addr_bean_rel.bean_id AS bean_id,
email_addresses.email_address AS email,
qs_quotationinformation.takenup AS takeup,
email_addr_bean_rel.email_address_id AS email_id
FROM
accounts
LEFT JOIN
campaigns ON accounts.campaign_id = campaigns.id
LEFT JOIN
users ON accounts.assigned_user_id = users.id
INNER JOIN
accounts_cstm ON accounts.id = accounts_cstm.id_c
LEFT JOIN
email_addr_bean_rel ON accounts.id = email_addr_bean_rel.bean_id
LEFT JOIN
email_addresses ON email_addr_bean_rel.email_address_id = email_addresses.id
LEFT JOIN
qs_quotamation_accounts_c ON accounts.id = qs_quotamation_accounts_c.qs_quot108funts_ida
LEFT JOIN
qs_quotationinformation ON qs_quotamation_accounts_c.qs_quotdb81tion_idb = qs_quotationinformation.id
WHERE
accounts.deleted = 0";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
if($row["NLC"] == 1 || $row["takeup"] == 1){$NLC = "No";}else{$NLC = "Yes";}
echo '<tr><td>'.$row['business'].'</td><td>'.$row["style"].'</td><td>'.$row["ren_date"].'</td><td>'.$NLC.'</td><td>'.$row["person"].'</td><td>'.$row["campaign"].'</td><td>'.$row["exec_fn"].' '.$row["exec_sn"].'</td><td>'.$row["email"].'</td><td>'.$row["takeup"].'</tr>';
}
} else {
echo "0 results";
}
In this case Table 1 is "accounts" and Table 2 is "qs_quotationinformation".
There are some accounts in Table 1 which have multiple records in Table 2, and some of the "takenup" records in Table 2 (relating to the same account) can be 1 and some be 0.
So what I need to do is have it so that if any of the records in Table 2 = 1, then all of the variables of $NLC need to = "No".
I don't know if this is possible, or if there is a better way to get this information. The html table is missing data that gets pulled, but that's because the table is just a visual representation of the most important data to the user.
EDIT Tables (excluding personal data):
Table 1:
+----+---------+---------+
| id | name | deleted |
+----+---------+---------+
| 1 | example | 0 |
+----+---------+---------+
Table 2:
+----+---------+
| id | takenup |
+----+---------+
| 1 | 0 |
+----+---------+
| 2 | 1 |
+----+---------+
| 3 | 0 |
+----+---------+
All of the rows in Table 2 relate to the row in Table 1. But because there is a row with takenup = 1 $NLC needs to return "No" and not "Yes" (which it currently does because the last related row is 0)

Answer 1

So, if you understand you correctly, if you have an account, that has a corresponding qs_quotationinformation.takenup value of 1, then the query should return "No" for accounts_cstm.nolongercontact_c AS NLC for all records with the same account id, regardless of the value of qs_quotationinformation.takenup field in the other records.
In this case you need to get the list of accounts that have qs_quotationinformation.takenup=1 and you can use a subquery to return this information, which can be left joined to the main query. accounts_cstm.nolongercontact_c AS NLC would be changed to a case expression to return the "No" value based on the subquery.
SELECT
accounts.name AS business,
accounts.industry AS style,
accounts_cstm.renewaldate_c AS ren_date,
case
when no_nlc.qs_quot108funts_ida is null then accounts_cstm.nolongercontact_c
else 'No'
end AS NLC,
accounts_cstm.contactname_c AS person,
campaigns.name AS campaign,
users.first_name AS exec_fn,
users.last_name AS exec_sn,
email_addr_bean_rel.bean_id AS bean_id,
email_addresses.email_address AS email,
qs_quotationinformation.takenup AS takeup,
email_addr_bean_rel.email_address_id AS email_id
FROM
accounts
LEFT JOIN
campaigns ON accounts.campaign_id = campaigns.id
LEFT JOIN
users ON accounts.assigned_user_id = users.id
INNER JOIN
accounts_cstm ON accounts.id = accounts_cstm.id_c
LEFT JOIN
email_addr_bean_rel ON accounts.id = email_addr_bean_rel.bean_id
LEFT JOIN
email_addresses ON email_addr_bean_rel.email_address_id = email_addresses.id
LEFT JOIN
qs_quotamation_accounts_c ON accounts.id = qs_quotamation_accounts_c.qs_quot108funts_ida
LEFT JOIN
qs_quotationinformation ON qs_quotamation_accounts_c.qs_quotdb81tion_idb = qs_quotationinformation.id
LEFT JOIN
(SELECT
qs_quot108funts_ida
FROM
qs_quotamation_accounts_c
INNER JOIN
qs_quotationinformation ON qs_quotamation_accounts_c.qs_quotdb81tion_idb = qs_quotationinformation.id
WHERE
qs_quotationinformation.takenup = 1) no_nlc ON accounts.id = no_nlc.qs_quot108funts_ida
WHERE
accounts.deleted = 0
The case expression assumes that accounts_cstm.nolongercontact_c field is of a string type (char, varchar, etc). If this is not the case, then you need to cast the value of accounts_cstm.nolongercontact_c field to char using the cast() function.
